Abstract

An incoming direction estimating unit (106a, 106b) estimates incoming directions for respective communication terminals. A grouping judging unit (107) divides communication terminals belonging in a sector into a plurality of groups based estimated incoming direction results. A scramble code allocation control unit (114) performs an allocation control so as to allocate the same scramble code to channels having similar directivities (not necessarily completely the same).
